Thirty-seven cases with laryngeal anomalies were observed at our department for tne past five years. There were 20 cases with laryngomalacia, 13 with recurrent nerve paralysis, 5 with subglottic stenosis, and one with laryngeal web. Symptoms include stridor, hoarseness, and dyspnea. Some cases had other anomalies, such as cardiac, or central nervous system. Two patients died of such complications. The prognoses were good in the vast majority of the cases. No active therapy was necessary, except in two cases, in whose subglottic stenosis were aggravated, and tracheostomy needed. Diagnoses were mainly made by laryngoscopy. For inspection of the subglottic space, X-ray pictures were used. Recently, energy subtraction computed radiography has been used for this inspection. With this technique, the spinal shadow is excluded, and the condition of the airway can be clearly observed. A representative case, in which this type of radiograph was useful, is reported.
